Col. C. Swinhoe on new Indian Butterflies. 359 



Underside : fore wing white ; basal and costal area for 

 two thirds of its length thickly irrorated with grey, and a few 

 submarginal grey lunular marks ; apical area and the entire 

 surface of hind wing tinged with yellow : hind wing with a 

 touch of ochre on the costa at the base ; a thin sprinkling of 

 grey irrorations on the subcostal vein and first branch, and 

 another thin sprinkling of grey atoms across the wing, passing 

 just inside the end of the cell and turning upwards towards 

 the apex. 



? . Above and below very much the same as in that sex 

 of A. zelnrira, but altogether whiter, the cliscal white area 

 running in on the median vein to the base of the fore wing ; 

 the submarginal yellow spots smaller and the marginal brown 

 band of the hind wing narrower. 



Expanse of wings, $ $ ly 2 o to 1-^ inch. 



Maldah, April and May 1886. 



Allied to A. zelmira, Cram. ; differs considerably in the 

 male in the paler colour of the black markings above, in the 

 absence of the large black marginal spots of the hind wing, 

 and underneath in the absence of the black veins. 



9. Appias Irvinii, n. sp. 



$ . Upperside white : fore wing with a blackish costal line, 

 some grey irrorations on the costal area along two thirds of its 

 length and some at the base ; a black apical patch covering 

 nearly one third of the costa at the apex and narrowing down 

 the outer margin to the second median branch, its interior 

 margin irregular and curved into the patch at its centre, the 

 veins in the patch white : a small marginal spot on the first 

 median branch and two or three small indistinct marginal 

 spots on the veins in the hind wing. 



Underside : fore wing white, some costal and basal irrora- 

 tions as above ; apical space and the entire surface of hind 

 wing tinged with yellow ; a few grey irrorations crossing the 

 end of the cell, otherwise both wings are without marks. 



? . Upperside white. Fore wing with a broad blackish 

 longitudinal band from the base to the end of the cell, com- 

 pletely filling its upper two thirds, continued up to the black 

 costal line in a suffused form, and attached to the black mar- 

 ginal border by a black band on the third median branch, 

 this band filling one third of the costa at the apex, is broader 

 than in the male ; it also has white veins, its inner margin 

 curves in a similar manner, but is more irregular, forms two 

 teeth on the first and second median branches, and is con- 

 tinued to the hinder margin ; base of wing broadly suffused
